Even at this stage, the features are recognisable – this is a baby Scarlet Macaw. A team of parrot experts are trying to rebuild the wild populations of one of the most colourful parrots in the world. Every newly hatched parrot baby is nurtured until it is fit for release.

In Argentina, Burrowing Parrots have established colonies in local towns, and in Phoenix, Arizona, the saguaro cactus provides an ideal home for the charming lovebirds from Africa.
